An ordinary stone with a pattern laser engraved on it can be sold for 20 or 30 US dollars. As long as you have a laser marking machine, you can use it to make money. For example, you can use a laser marking machine to engrave text and patterns on various materials in your own store, workshop, home, or even a street stall. It can be customized in batches and you can make a lot of money in a day. Do you want to own a laser marking machine that can make money? You can purchase from me for wholesale or retail.
